Hi, I am having a crank no start issue good battery good airflow good starter Idk about spark or fuel. A
ll I hear is a constant buzzing sound that originates from the engine bay I am including what is buzzing if anybody can tell me what this is I would appreciate it greatly
More information is needed to move forward. First, what year, model, engine, trans etc do you have. Next get your codes pulled. Then verify spark and fuel. Finally, there is a lot of stuff in that picture. Please edit the pic with a circle where you think you are hearing your mystery sound.
You will have to determine if it's lacking spark or fuel, which is a very simple process and is needed in order to diagnose the actual problem. I wouldn't worry about that item in the pic at this point in time, bigger fish in the pan to fry.
I found out it is a pressure regulator it is getting a good spark (just changed the plugs and tested) so I am guessing fuel rail problems or the injectors possibly it has fuel to the regulator but IDK what psi
Still need to spray some starter fluid (or other) in the intake and crank it to see if it responds as it should. This, to rule out the spark occurring at the wrong time.
